GE Refrigerator Error Code: SA 66
Another code that confuses people, SA 66 means the refrigerator is in Sabbath Mode. Sabbath Mode is designed for certain religious observances and holidays. If the refrigerator is in Sabbath Mode, it will affect the defrost function, the ice maker, dispenser, and touch control panels.
Sabbath Mode can be turned off by pressing both the minus and temperature keys for five seconds.
